Capsize

These are 80,000 dwt and over. They normally carry cargoes such as iron ore, coal and so on.

Panamax

50,000-80,000 dwt typical cargoes include coal, fertilizer and so on. They are the largest vessels which can pass through the Panama Canal.

Handymax

35,000-50,000 dwt. They carry a wide range of bulk cargoes such as fertilizer, scrap etc.

Handysize

10,000-35,000 dwt. They carry general bulk solids.

OBO

OBO stands for ‘ore/bulk/oil’ and the vessels are sometimes called combined carriers. They can carry solids (ore and bulk cargoes) and crude oil, but not at the same time.

PROBO

PROBO stands for ‘product ore/bulk/oil’. They carry the same cargo as OBOs, but can also carry refined petroleum products. This is because the cargo holds are usually coated with a cargo tank coating.

Container ship

These carry a cargo of containers on scheduled routes. Size is normally measured in teu (the size of a 20 foot standard container). The biggest can be up to 8100 teu.

Generalcargo

These are small vessels carrying a wide range of paletted and individual cargoes-for instance, machinery, drums, bags and so on.

RORO

RORO stands for ‘roll on, roll off’. These vessels carry road and rail vehicles and can be unloaded by wheeled transport.

Car carrier

Car carrier, or vehicle carriers, carry newly manufactured cars.

Reefer

Reefers are refrigerated cargo vessels. They are similar to general cargo vessels, but the holds are refrigerated. They usually carry perishable foods like and meat.

FPSO

FPSO are floating production storage and offloading vessels. They take crude oil from undersea wells, process it and store it before loading it into tankers to be carried to a refinery or land storage.

There are a number of vessels designed to carry the particular type of cargo they named after- for instance, wood chip carrier, cement carrier. They have a similar design to tankers (for specialize liquids) or bulkers (for particular cargoes). They are also likely to have specialized equipment.

he seabed, which requires additional power, especially if the nets are equipped with disturbing chains to churn up the sea floor. The construction and equipment of these fishing vessels strongly depend on the fishing method and the species of fish aimed at. The most important types of trawlers are the cutter and the stern trawler.
